All the resistor are connected in series.so,

  • Combined resistance (R) = 0.2 + 0.3 + 0.4 +0.5 + 12

  • Combined resistance (R) =13.4Ω

  • Potential difference (V) = 9 v

  • Current (I) = ?

Current flow through the whole circuit can be calculated by using ohm's law:-

\bf\:\dfrac{V}{I}=R

\bf\:\dfrac{9}{I}=13.4

\bf\:I=\dfrac{9}{13.4}

\bf\:I=0.67\:ampere

Since the same current flows through all the resistors connected in series in a circuit,therefore 0.67 ampere of current would flow through the 12Ω resistor.
